Verizon is the place to go. I picked up my W140 out of state and Alltel said they couldn't help me. They can locate your ESN and turn you on within 30 minutes. They had something similar to a sniffer that picked up the ESN while they held it next to the car while they placed a call from the car. They had to use this equipment because the tech forgot how to manually go through the menu to get it.
